I'd like to test radiator (2.16.3 on hp-ux 11, perl5.6. authbyldap2)
under heavy load scenarios, to help plan for servers. What I'd like to
do is have some data that allows me to plot average response time vs the
number of simultaneous requests. (Say with the latter ranging through
2,5,10,50,100,1000,10000,50000 or until radiator breaks ;))
I've looked at radpwtst, but whilst -iterations and -time are useful,
they serialise the requests, whereas I want to simulate nnnn NASes all
sending requests at the same time.
What is the best way to do this?
I could write a driver script that started nnnn copies of radpwtst in
the background, each one sending xxxxx iterations and timing the
results, but this leads to other issues (like, nnnn processes competing
amongst each other for resource. Maybe the sticky bit would help, like
in the old days?)
Help gratefully received,
--herb
